Pi UpMix

Welcome

Pi UpMix by Saharty turns stereo (or mono) into surround and immersive sound. It takes a finished stereo mix and spreads it across every speaker in the room, from a simple LCR up to a 16-channel 9.1.6 layout, or renders it to headphones, Lo/Ro, Lt/Rt or Ambisonics. It also works as a format converter: feed it a 5.1 or 7.1.4 bed and it carries every channel to the matching speaker of a bigger or smaller layout.

Its signature feature is Downmix lock. With the lock on (the default), the upmix is built so that the standard stereo fold-down of the result gives back your original stereo exactly. There are no phase tricks and no comb filtering: the version most people will hear, the stereo one, stays untouched. On our test material the fold-down null measures about -138 dB on every layout.

Pi UpMix is made for:

• Studio engineers delivering surround and immersive versions of catalogue releases, live recordings, film and broadcast material from stereo masters.
• Live and installation engineers feeding surround and overhead speakers in clubs, theatres and installations from a stereo playback or a console bus, in real time.
• Anyone without an immersive room, who can monitor the full layout on headphones with the built-in binaural renderer.

It comes as VST3, Audio Unit (macOS), AAX and a standalone app for macOS and Windows. The standalone app adds an offline file renderer.

What's new in version 1.1

• Stem separation (Stems tab, off by default). When you turn it on, the mix is split into vocal, drums, bass, instruments and ambience, and each part is placed on its own. It is still exact with Downmix lock.
• Stem objects output: the eight stems go to the first eight outputs, and their positions can be sent to an object renderer over ADM-OSC.
• Room regeneration (Space tab, creative mode): measures the decay of the room in your source and regenerates a matching room in the surround and height speakers.
• Fold-down guard: keeps an exact stereo fold-down even in creative mode with delays, diffusion and room.
• Spatial Match: learns how a reference surround or immersive mix uses its speakers and moves your upmix towards it, band by band.
• Head tracking for the headphone render, over OSC.
• Custom speaker layouts: type in your own speakers (up to 16).
• Live (5 ms) quality for live sound and broadcast.

Quick start

1. Run the installer for your system (macOS .dmg or Windows .exe) and restart your audio software.
2. Open Pi UpMix and click Activate... in the header. Enter your licence key and click Activate, or click Start 15-day free trial.
3. In your DAW, create a track or bus with the target layout (for example 7.1.4, 12 channels) and put your stereo source on its L and R channels, or use a stereo-in / multichannel-out insert where your host offers one.
4. Insert Pi UpMix by Saharty on that track.
5. Check the readout under the speaker map: it should say, for example, "Input Stereo, output 7.1.4".
6. Press play. The speaker map lights up as each speaker receives sound.
7. Choose a starting point from the preset menu, for example Music natural.
8. Adjust the Front, Surround and Height rows on the Main tab to taste.
9. Leave Downmix lock on and watch the Fold-down match readout: it confirms your stereo is preserved.
10. No speakers? Choose Monitor headphones in the monitoring menu to hear the whole layout binaurally on the L and R outputs.

Installation

macOS

1. Open the downloaded .dmg.
2. Double-click Install Pi UpMix by Saharty.pkg.
3. Click Customize if you want to choose the formats (VST3, Audio Unit, AAX, standalone app). By default all are installed.
4. Finish the installer and restart your audio software. Look for Pi UpMix by Saharty from the manufacturer Saharty.

The .dmg also contains Uninstall Pi UpMix.command, which removes everything.

Note: If macOS says the installer is from an unidentified developer, right-click the installer, choose Open, then Open again, or allow it in System Settings > Privacy & Security.

Windows

1. Run the setup .exe and follow the steps.
2. Restart your audio software.

Note: If Windows SmartScreen shows a warning, choose More info, then Run anyway.

Where the files go

Everything Pi UpMix needs is inside the installer. Nothing else has to be installed.

First launch

• Plug-in: insert it on a track. The window opens at its default size; drag the bottom-right corner to resize it (from 780 x 495 up to 1560 x 990, aspect ratio fixed). The size is remembered with the session.
• Standalone app: open Pi UpMix by Saharty from Applications (macOS) or the Start menu (Windows). On macOS the app asks for permission to use audio input, since it processes live sound from your interface. Use the app's audio settings to choose your audio device and the input and output channels.

Using it in your DAW

Discrete channel orders (Reaper and other hosts that only know a channel count, and the files written by the standalone renderer):

Hosts that name their channels (Pro Tools, Logic Pro, Cubase, Nuendo) can use any of the named layouts: LCR, LCRS, quad, 5.0, 5.1, 6.0, 6.1, 7.0, 7.1, 5.0.2, 5.1.2, 5.0.4, 5.1.4, 7.0.2, 7.1.2, 7.0.4, 7.1.4, 7.0.6, 7.1.6, 9.0.4, 9.1.4, 9.0.6 and 9.1.6, or any other speaker set built from these speakers (up to 16 channels, with L and R present). An Ambisonics bus of order 1 to 3 is also accepted as the output.

Activation & licensing

Pi UpMix is licensed per computer: one licence activates one computer, and you can move it at any time. The VST3, AU, AAX and standalone versions on one computer share the same licence, so you activate only once.

Buying and the free trial

• Buy Pi UpMix at pi-ware.com. Your licence key arrives by email after purchase.
• You can try every feature free for 15 days. No payment details are needed. Start the trial from the licence window (Start 15-day free trial).
• You get free updates.

The licence window

Click the licence button in the header to open the licence window. The button's label tells you the state at a glance:

When there is something to tell you, a banner also appears across the top of the window; click it to open the licence window.

The licence window shows the current status, This computer: with the computer's name, a Licence key field and these actions:

• Activate: activates the key you typed (format XXXXX-XXXXX-XXXXX-XXXXX).
• Start 15-day free trial: shown while the computer is not activated or on a trial.
• Deactivate this computer: frees this computer so the licence can be used elsewhere.
• Offline activation: shows the offline steps.
• Buy a licence: opens the product's page on pi-ware.com.

How to activate online

1. Click Activate... in the header.
2. Paste your licence key in the Licence key field.
3. Click Activate (or press Return). The status line changes to "Activated ... Every feature is on."

How to activate offline

Use this when the computer running Pi UpMix has no internet connection.

1. Type your licence key in the Licence key field first.
2. Click Offline activation. A request code appears.
3. Click Copy code and take the code to any device with internet access.
4. Paste the code at pi-ware.com/activate. You receive a licence file.
5. Bring the file back and click Load licence file... to load it (.pilic file).

Moving the licence to a new computer

• From the old computer: open the licence window and click Deactivate this computer, then activate on the new one.
• If you no longer have the old computer: just activate on the new computer. Pi UpMix tells you the licence is active on another computer and asks whether to move it (Move it here). The dialog also shows how many moves you have left this year. The old computer gets a 24-hour notice, then switches to limited features.
• You can also deactivate or reset computers from your account at pi-ware.com/account.

Checks, notices and limited mode

• Pi UpMix checks the licence whenever it finds an internet connection (at launch, then every hour). It keeps working offline with no time limit.
• Nothing is ever limited without at least 24 hours of notice on that computer (for example after the licence was moved, the trial ended or the computer was deactivated from your account). During the notice every feature works and the banner shows the countdown.
• In limited mode (or when not activated) the audio passes through unprocessed, with a short 50 ms crossfade: the input goes to the matching output channels (L to L, R to R, the other speakers silent), with the same latency as the upmix, so your session stays in sync. The window, controls and presets stay available. In the standalone app the render button shows Activate to render.

Licence file location

Interface tour

The window has four areas: the header across the top, the speaker map on the left, the tabs with the controls on the right, and the meter strip along the bottom.

Header

Speaker map and monitoring

The speaker map shows every speaker of the current output, seen from above with the front at the top, and lights each one with its live level.

• Click a speaker to solo it. Click more speakers to add them to the solo.
• Right-click a speaker to mute it.
• Clear solo clears every solo and mute.

Below the map:

Note: Solo, mute and the monitoring menu are checking tools. They are not saved with presets.

Tabs

The controls are on four tabs: Main, Detail, Stems and Space. Controls that only work in creative mode are dimmed while Downmix lock is on. Stem controls are dimmed until stem separation (or the Stem objects output) is on. Hover over any control to see a tooltip.

Turn a knob by dragging; the value appears with its unit. Typing a value is also possible where your host's generic parameter view allows it (frequencies accept "k", for example "1.2k").

Main tab

Detail tab

Stems tab

Space tab

Meter strip

Along the bottom you find the Input meters (L and R), the Correlation readout of the input (+1 is mono, 0 is wide, negative values mean out-of-phase content), and one output meter per channel, labelled with the speaker names of the current layout (for example L, R, C, LFE, Lss ...). With the Stem objects output the meters are labelled Vocal, Drums L, Drums R, Bass, Other L, Other R, Ambience L and Ambience R.

Upmixing stereo to speakers

This is the core workflow: a stereo source into a multichannel speaker layout.

How it works

Pi UpMix analyses the stereo signal frequency by frequency. It separates the direct sound (anything panned somewhere between the speakers: vocals, instruments, dialogue) from the ambience (the room, the reverb, the wide and diffuse parts). The direct sound stays in the front, with the centered part anchored in the center speaker; the ambience goes to the surrounds and heights; the lowest frequencies can feed the LFE.

How to set up a basic upmix

1. Insert Pi UpMix on a track with your target layout (see Installation).
2. Load Default balanced (downmix safe) or Music natural from the preset menu.
3. On the Main tab, set the Front row: - Raise Center to anchor vocals and dialogue more firmly in the center speaker; lower it for a more phantom, stereo-like front. - Reduce Center width if instruments panned slightly off-center are being pulled into the center. - On 9.x layouts, use Wides to send hard-panned sound to the wide speakers. - Use Height lift to raise part of the front image into the top front speakers.
4. Set the Surround row: Amount for how much ambience reaches the surrounds, Side to rear to move it from the side towards the rear speakers.
5. Set the Height row: Amount for the heights, Front to rear to balance between top front and top rear speakers.
6. Check the result with the speaker map and the solo function (click a speaker to hear it alone).

How to fine-tune the analysis

On the Detail tab, the Analysis row controls how the direct sound and ambience are told apart:

• Sensitivity: higher values treat more of the signal as ambience, so more goes to the surrounds and heights. Lower values keep more in front.
• Response: how fast the analysis follows the music. Short times (tens of milliseconds) react quickly to changes; long times (100 ms and more) give a calmer, steadier image, which suits classical and acoustic recordings.
• Transient guard: keeps attacks (drum hits, plucks, consonants) in the front speakers, so they do not smear into the surrounds.

The Low cuts row keeps bass where it belongs: below Center the bass stays in L and R, below Surround it stays in the front speakers, and below Height it stays out of the height speakers.

How to use the LFE

1. Make sure LFE is on (Main tab, LFE and output row). The LFE channel only exists in .1 layouts.
2. Set LFE cutoff (the upper frequency of the LFE feed) and LFE level.

The LFE is an extra feed: the main speakers keep their bass. With a bass-managed system you may want LFE off, or a low level.

How to upmix a mono source

1. On the Detail tab, set Input mode to Mono (L+R), or Left only / Right only to use one side.
2. Turn Downmix lock off and use Mono spread (Input row) to spread the mono source into the room.
3. Or simply load the Mono to surround factory preset.

A mono input bus (one channel) is also accepted and is treated as a center source.

Downmix lock and creative mode

Downmix lock

With Downmix lock on, every speaker feed is a phase-free combination of the input, chosen so that the standard stereo fold-down returns the input exactly:

L' = L + 0.707 x (C + every left-side speaker), and the same on the right. A centre surround speaker folds at 0.5 into both sides, and the LFE is left out.

The Fold-down match readout under the speaker map shows the result live. With the lock on it reads about -100 dB or lower, and often "exact (below -150 dB)". In other words: when your immersive mix is folded down to stereo by a player, a renderer or a broadcast chain, your original stereo master comes back.

Creative mode

Turn Downmix lock off to enter creative mode. Pi UpMix keeps the overall energy constant, and these controls become available (they are dimmed while the lock is on):

• Surround and height Delay and Diffusion (Main tab)
• Input Width and Mono spread (Detail tab)
• Trims for front, center, surround, height and wide speakers (Detail tab)
• Stem levels (Stems tab)
• Room regeneration and Fold-down guard (Space tab)

Delay pushes the surround or height speakers slightly later so the front image stays forward (precedence). Diffusion decorrelates the speakers for a wider, more enveloping sound.

How to keep the fold-down exact in creative mode

1. Turn Downmix lock off and set your delays, diffusion and room.
2. On the Space tab, raise Fold-down guard. At 100 % the stereo fold-down stays exact, because L and R are corrected for what the creative processing added.
3. Watch the Fold-down match readout ("(creative mode)" is added to it).

Tip: Use creative mode for live rooms, installations and deliberate effects. When the stereo fold-down must stay pristine (catalogue releases, broadcast), keep the lock on, or use Fold-down guard at 100 %.

Stem-aware upmixing

New in version 1.1. Pi UpMix is a normal upmixer until you set Separation to On, choose the Stem objects output, or load one of the Stems presets. Until then the separation does not run and its controls are dimmed.

When it is on, the mix is split into five parts using fast signal processing: vocal, drums, bass, instruments and ambience. Each part is placed on its own:

• The lead vocal goes to the center, with optional lift into the top front speakers.
• Drum hits stay in front instead of leaking into the center or the surrounds.
• The bass stays solid in the front speakers below the Bass split frequency.
• Instruments can be pushed to the sides or up.
• The ambience feeds the surrounds and heights.

Stem-aware upmixing is still exact with Downmix lock (fold-down null about -138 dB).

How to place the stems

1. On the Stems tab, set Separation to On (or load Stems: natural (downmix safe)).
2. Vocal row: To center sets how much of the lead vocal moves into the center speaker; Width sets how wide a pan range counts as the lead vocal; Lift raises part of it into the top front speakers.
3. Drums row: Position is the angle on each side (30° = the front L/R speakers, 90° = the sides, up to 150°). Height raises them towards the heights; Spread spreads them over neighbouring speakers.
4. Instruments row: the same three controls for guitars, keys and other instruments.
5. Bass split: below this frequency the bass stem stays in the front speakers.
6. In creative mode (lock off), balance the parts with the Stem levels row.

Tip: Start with Stems: wide stage for a bigger, more spacious band image, or Stems: creative room to add a regenerated room as well.

Stem objects and ADM-OSC

For object-based workflows, Pi UpMix can output the stems as eight separate objects instead of speaker feeds.

How to output stem objects

1. Give the track at least 8 output channels.
2. On the Stems tab, set Output to Stem objects.
3. The first eight outputs now carry: Vocal, Drums L, Drums R, Bass, Other L (instruments left), Other R, Ambience L, Ambience R. The layout readout says "output 8 stem objects" and the meters show these names.

If the track has fewer than 8 channels, Pi UpMix keeps the normal speaker output.

How to send object positions to a renderer

1. Go to the Space tab, Objects row.
2. Enter the Renderer address (IP address; 127.0.0.1 for the same computer) and Port (default 9000). Press Return or click elsewhere to apply.
3. Click ADM-OSC so it reads On.

While the Stem objects output is active, Pi UpMix sends each object's position ten times a second using the ADM-OSC messages /adm/obj/n/aed (azimuth, elevation, distance 1.0) and /adm/obj/n/w (width), where n is 1 to 8 in the order above. The positions follow your Stems tab settings:

Positive azimuth is to the left. Map the eight output channels to the renderer's objects 1 to 8.

Format conversion and downmix

Pi UpMix can also convert between multichannel formats.

How to convert a multichannel bed

1. Set the track's input to the source format (for example 5.1) and the output to the target (for example 7.1.4). In Pro Tools, the AAX version supports this when input and output are the same multichannel format and the source sits on the matching channels; otherwise use a host that offers different input and output formats.
2. On the Detail tab, set Source to All input channels.
3. L and R are upmixed as usual, and every other input channel (C, LFE, surrounds, heights ...) is carried to the matching output speaker.

This works both ways: 5.1 to 7.1.4, or 7.1.4 to 5.1. It is also exact with Downmix lock.

Stereo, headphone and Ambisonics outputs

Stereo outputs

When the output is stereo (2 channels), the Stereo output menu on the Detail tab chooses what you get:

• Headphones (binaural): a binaural render of the full virtual layout, for listening on headphones.
• Lo/Ro fold-down: a standard left-only/right-only fold-down.
• Lt/Rt matrix: a matrix-encoded stereo.

Virtual layout chooses the speaker layout that is rendered: 5.1, 7.1, 7.1.4 (default) or 9.1.6.

Headphone monitoring of a speaker output

You do not need a stereo track to check your work on headphones. With any speaker output, choose Monitor headphones in the monitoring menu under the speaker map. The binaural render plays on the L and R outputs. Monitor stereo fold-down lets you hear exactly what a stereo fold-down of your upmix will sound like. Switch back to Monitor speakers before you print.

How to use head tracking

1. On the Space tab, Head tracking row, set the OSC port (default 8000) and press Return.
2. Configure your head tracker (or its app) to send OSC to this computer on that port. Pi UpMix understands: - yaw, pitch and roll in degrees in one message whose address ends in /ypr, /rotation or /head; - a quaternion (w, x, y, z) in a message whose address contains quaternion; - separate messages ending in /yaw, /pitch and /roll.
3. Turn Tracking on. The Tracker readout shows "Receiving, yaw ..." while data arrives.
4. Face the front and click Recenter.

Head tracking turns the headphone render with your head, so the speakers stay in place in the room as you move.

Ambisonics output

If the track's output is an Ambisonics bus (1st, 2nd or 3rd order), Pi UpMix renders the virtual layout to Ambisonics in the AmbiX convention (ACN channel order, SN3D normalisation). The Virtual layout menu chooses which layout is encoded.

Room regeneration

New in version 1.1, in creative mode. Pi UpMix measures the decay of the room in your source and regenerates a matching room in the surround and height speakers.

How to add a regenerated room

1. Turn Downmix lock off.
2. Go to the Space tab, Room row. Play the source for a while: Source decay shows the decay time measured from the source.
3. Raise Amount.
4. Leave Decay at Match source to follow the measured decay, or turn it up to set a fixed decay time (up to 8 s).
5. Shape the room with Damping (how quickly the high frequencies fade) and Size (50–200 %).
6. If the stereo fold-down must stay exact, raise Fold-down guard.

Spatial Match

New in version 1.1. Spatial Match learns how a reference surround or immersive mix uses its speakers and moves your upmix towards it, band by band. It works with Downmix lock on and stays exact.

How to match a reference mix

1. Go to the Space tab, Match row, and click Learn....
2. Choose a multichannel reference file (WAV, AIFF, FLAC or CAF with 3 to 16 channels). Pi UpMix reads it in the background.
3. Reference status shows "Learned " when it is done.
4. Raise Spatial match to move your upmix towards the reference.

Note: The learned reference is saved with your session, not in presets. The Spatial match amount is saved in presets.

Custom speaker layouts

New in version 1.1. If your room does not match a standard layout, type in your own speakers.

How to create a custom layout

1. Go to the Space tab, Speakers row, and click Edit....
2. Type one speaker per line, in output channel order: name, azimuth and elevation in degrees. Add the word lfe for a subwoofer. For example:

L 30 0 R -30 0 C 0 0 SUB 0 0 lfe LS 110 0 RS -110 0 TFL 45 45 TFR -45 45

• Azimuth is positive to the left (-180 to 180); elevation is -90 to 90.
• Use between 2 and 16 speakers.
• Spaces, tabs, commas or semicolons separate the values; anything after # is a comment. 3. Click Apply. The editor shows "Applied: N speakers", or an error explaining which line is wrong. 4. Click Close, then turn Custom layout On. 5. Give the track the same number of channels as speakers. The Layout readout says "N speakers, active" when it is in use, or "give the track N channels" when the channel count does not match yet.

The custom layout is saved with your session.

Presets and A/B comparison

Factory presets

Loading a factory preset first resets all settings to their defaults and then applies the preset. The factory presets also appear in your host's program list.

How to save and load your own presets

1. Click Save. A name field appears in place of the preset menu.
2. Type a name and press Return (Escape, or clicking elsewhere, cancels).
3. Your preset appears in the User section of the preset menu and in the < / > order after the factory presets.

User presets are saved as .piupmix files in Documents/Saharty/Pi UpMix/Presets. You can copy them to another computer.

Note: Presets do not store Quality, Bypass, the stem Output choice or Tracking, so loading a preset never changes your latency or routing.

How to compare two settings

1. Set up a sound in slot A.
2. Click Copy to copy it to slot B, then click B.
3. Change settings in B.
4. Switch between A and B to compare instantly.

Rendering files (standalone app)

The standalone app includes an offline renderer that upmixes whole files with the current settings at high quality.

How to render a file

1. Set up your sound in the standalone app (presets, tabs, Spatial Match ...).
2. Click Render file... (shown as Activate to render until Pi UpMix is activated or the trial is running).
3. Choose the Output: any speaker layout from LCR to 9.1.6 (default 7.1.4), Headphones (binaural stereo), Lo/Ro stereo, Lt/Rt stereo, Stem objects (8 channels) or Ambisonics order 1–3 (AmbiX).
4. Choose the File format: 32-bit float WAV (default) or 24-bit WAV.
5. Turn on Mono stems if you want one mono file per channel instead of one multichannel file.
6. Click Choose file and render... and choose a stereo or mono audio file (WAV, AIFF, FLAC, MP3 or OGG; on macOS also M4A and CAF).
7. Watch the progress bar. When it says "Done: ...", click Show in folder.

The result is written next to the source file:

• One file: <name> (Pi UpMix <output>).wav, in the channel order shown in the table under Installation.
• Mono stems: a folder <name> (Pi UpMix <output>) stems containing files such as Song.L.wav, Song.C.wav.

The output is aligned with the source (the processing latency is removed). A file that would exceed 4 GB is written as mono stems automatically. Cancel stops the render and keeps the partly written files.

Settings & preferences

Quality and latency

The Quality menu (Detail tab) sets the frequency resolution of the analysis. Higher resolution separates sounds more finely but adds latency. The latency is always reported to the host, so your session stays in sync, and it is shown under the speaker map.

At 88.2/96 kHz and 176.4/192 kHz the sample counts double and quadruple, so the latency in milliseconds stays about the same. Changing Quality briefly reconfigures the processing; it is not automatable. The offline renderer always uses high quality.

What is saved

• With the session (host project): every parameter, the current preset name, the window size, the custom layout and its on/off state, the head-tracking port, the ADM-OSC settings and the learned Spatial Match reference.
• In presets: all sound parameters (not Quality, Bypass, stem Output or Tracking).
• Not saved: solo, mute, the monitoring menu, and the A/B slots.

Automation

All parameters can be automated from your host except Quality and the stem Output choice, which change the processing structure.

Window size

Drag the window corner to resize it between 780 x 495 and 1560 x 990. The layout scales as a whole and keeps its proportions.

Keyboard shortcuts / remote control

Keyboard

OSC input: head tracking

Port: OSC port on the Space tab (default 8000, UDP). Yaw is positive to the left, pitch positive up, roll positive to the right. Use Recenter to set the front.

OSC output: ADM-OSC object positions

Destination: Renderer address and Port on the Space tab (default 127.0.0.1:9000). Sent only while ADM-OSC is on and the Stem objects output is active.

Pi UpMix does not use MIDI or timecode.

Tips for live/studio use

Studio

• Keep Downmix lock on for deliverables. Your stereo master survives any fold-down. Use the Fold-down match readout as your proof.
• Use High quality for the final print. Standard is fine while you work; switch to High quality before you bounce, or render with the standalone app, which always uses high quality.
• Check the fold-down and headphones without rerouting. The monitoring menu's Monitor stereo fold-down and Monitor headphones play on L and R, so you can check on the same speakers or headphones. Remember to return to Monitor speakers.
• Dialogue and vocals: raise Center and Transient guard, and use Center low cut so the center speaker does not get muddy. The Film and broadcast dialog preset is a good start.
• Acoustic and classical: a slower Response (100 ms and more) and a lower Transient guard give a calmer, more natural hall.
• Busy pop and rock mixes that smear into the surrounds benefit from stem separation: drums stay in front, the vocal stays centred.
• Match a house style with Spatial Match: learn one of your own finished immersive mixes and apply it to new upmixes for consistent results across an album.

Live

• Use Live (5 ms) quality to keep the processing delay small enough to stay with the stage sound.
• Creative mode works well in rooms: surround Delay keeps the image anchored to the stage (precedence), and Diffusion helps the surrounds sound enveloping rather than like extra loudspeakers. Try Live concert hall or Electronic club.
• Bypass keeps the latency, so toggling it never shifts your timing.
• Use custom layouts for venues and installations whose speakers are not in standard positions.
• Give it its own computer or bus: in the standalone app you can feed Pi UpMix from a console bus through your audio interface and send the outputs straight to the surround and overhead speakers.
